Chapter 8, Problem 94P(choose chapter or problem)
Silicon, which occurs in nature as \(\mathrm{SiO}_{2}\), is the material from which most computer chips are made. If \(\mathrm{SiO}_{2}\) is heated until it melts into a liquid, it reacts with solid carbon to form liquid silicon and carbon monoxide gas. In an industrial preparation of silicon, 52.8 kg of \(\mathrm{SiO}_{2}\) reacts with 25.8 kg of carbon to produce 22.4 kg of silicon. Determine the limiting reactant, theoretical yield, and percent yield for the reaction.

ANSWER:
Step 1 of 4
Balanced equation:
Find the moles of each:
Grams -> moles
Given kg 
1000 g/1 kg 1 mol/molar mass
Molar mass 
Molar mass C: 12.01 g/mol
57.8 kg 1000 g 1 mol
25.8 kg C 1000 g C/1 kg C 1 mol C/12.01 g C = 2148.21 mol C
